Yes, you were spot on. I had the mu in my nearCallback function as dInfinity 
and mu2 as 0. The car now steers, but the sim goes nuts when I do after a few 
seconds? First the car starts sliding around as if on ice, then topples over, 
and the sim explodes. Could it be the CFM value perhaps?

Are there any more detailed explanations of the mu values for collisions in 
the Wiki area, the documentation doesn't say much.

Thanks again Martin.
